Weak, peeling, splitting nails don't need another coat of chemicals. They need feeding. Our Organic Nail Hardener is a nourishing oil-and-butter blend that strengthens nails from the base up, no formaldehyde, no toluene, no plastic shell that dries them out further. Just seven natural ingredients working on the nail plate and cuticle at the same time. Brush it on clean, bare nails. Let it absorb. Repeat daily. Within a few weeks, nails feel harder, break less, and grow longer before they give out.
